I see a typical load of security related bugfixes.
But what else changed between 10.15.2 and 10.15.3 ?

The update dialog mentioned a fix for Pro Display XDR and one other thing.

Trying to install the update on a Mac Mini with eGPU, the machine literally turns off. If you turn it back on, it will just turn back off a few seconds later. The eGPU must be disconnected (or turned off) for the Mac Mini to boot up and finish installing. I haven't tried rebooting since the install finished to see if it's capable of booting again with it connected. (10.15.2 broke eGPU booting on Mac Mini, which you'll see a bunch of comments asking about any time there was a 10.15.3 beta thread)
 
All I found in release notes was:
"
– Optimizes gamma handling of low gray levels on Pro Display XDR for SDR workflows when using macOS
– Improves multi-stream video editing performance for HEVC and H.264 encoded 4K video on the 16-inch MacBook Pro (2019)
"

Please do try it and share, I've been thinking to add an eGPU to my Mac mini 2018 for sometime but holding off exactly because many complaints since 10.15.2 release. The worst case is to add a portable screen for iGPU but I really don't want to spend on that just for workaround Apple's problem.

Thanks a lot!

On initial inspection it appears the behavior is the same as the previous release. I can't tell you if 10.15.3 fixed anything because I was already working around the problem, but probably not.

Specifically, 10.15.2 would not boot if an eGPU was connected and FileVault is enabled. I disabled FileVault to work around the problem because the SSD is encrypted by the T2 chip whether FileVault is enabled or not, and someone would need to physically steal the machine and have macOS on a USB drive to boot from in order to get at the data since I still have it booting to the lock screen. (Or run it in Target Disk mode attached to another mac, I guess?)

With 10.15.3 installed and FileVault disabled, I can still boot the 2018 Mac Mini with eGPU connected and the only display is connected to the eGPU. It does get boot screens. I'm using a Sonnet enclosure and a Radeon RX 5700 (Navi). I don't know if the FileVault problem is fixed, but initially it doesn't seem any worse than before. Rebooting still seems to be inconsistent, (sometimes screen goes back for the reboot, never boots back up and have to power it down) but cold boot seems fine.

This update fixed my Safari cookies problems I having since the last update but sometimes Safari pages will still lock-up with the wheel spinning and having to close the tab on top of that the iCloud Safari tabs still won't work 10 minutes after I open the app, so yeah, great.

Thanks a bunch! That's detail and first hand experience, so no better no worse, guess kinda a good news given recent Apple progress on eGPU boot time support ;)
Yeah, disabling FileVault is another route if the system is in private space...
 
Hasn't sorted the issue with a Radeon RX 5700XT and C4D ProRender, so assume GPU drivers still not updated, annoyingly. (I can use two RX 580s, but the moment I add the 5700 – boom, instant crash).
 
Mail bugs not completely squashed yet, so watch out (michael tsai's blog)
There’s nothing about it in Apple’s release notes, but from what I’ve heard macOS 10.15.3 fixes the bug where large numbers of messages stored “On My Mac” could be deleted when updating to Catalina or rebuilding Mail’s database. It does not fix the bugs where moving messages between mailboxes (via drag and drop, rules, or AppleScript) can delete them, duplicate them, or simply not move them at all.

There was a bug where thin white lines on a dark background, or small white objects on the same appeared cyan on the XDR; this was only with the 16" MBP. It's been fixed, so at least maybe a driver update for the 5500M?

Correction: Apparently at least one person I know that had this bug is now saying it wasn't fixed, so mixed results?
 
MacBook Pro 2019-16” on 10.15.3 still no fix for egpu missing on power up, have to power cycle or remove/insert TB3 cable after login. OpenCL in geekbench 5 still shows an AMD RADEON 5700XT (34k) has less performance than a 580 (40k).

So far Catalina has been bad for egpus.
 
Macbook Pro 2019-15, clean install 10.15.3, when i was doing disabling some of the services, found the following: if you disable CSRUTIL, there is no sound. Speaker greyed out. Enabling it back bring sound back to live. Interesting new approach by apple.
 
This update is over 3GB, and yet, there is little information about what it addresses, and very few posts about any kind of improvements. MacRumors didn't even post about this update (unless I missed it). I guess it's safe to assume the Music app didn't get any fixes or features added back in?

TV App is still doing the annoying thing where you have to click on the Movies tab a couple of times to be taken to the movies - first click always seems to take you to the "Watch Now", although "Movies" is still highlighted.
